3d expanded isometric bounds derived from the
data, similarily to type=2.Note that
axes boundaries can be customized through the axes
entity properties (see axes_properties).

box

an integer (frame around the plot).

box=0

nothing is drawn around the plot.

box=1

unimplemented (like box=0).

box=2

only the axes behind the surface are drawn.

box=3

a box surrounding the surface is drawn and
captions are added.

box=4

a box surrounding the surface is drawn, captions
and axes are added.Note that axes aspect can also be
customized through the axes entity properties (see axes_properties).
This is the default value.

ebox

It specifies the boundaries of the plot as the vector
[xmin,xmax,ymin,ymax,zmin,zmax]. This argument is
used together with type in
flag : if it is set to 1,
3 or 5 (see above to see the
corresponding behaviour). If flag is missing,
ebox is not taken into acoount. Note that, when
specified, the ebox argument acts on the
data_bounds field that can also be reset through
the axes entity properties (see axes_properties). The ebox default
value is [0,1,0,1,0,1].

Description

param3d is used to plot a 3D curve defined by its
coordinates x, y and
z. Note that data can also be got or modified through
the surface entity properties (see surface_properties).

Note that properties like rotation angles,
colors and thickness of the plotted
curves can also be got or modified through the polyline entity properties
(see polyline_properties).

Use param3d1 to do multiple plots.

Enter the command param3d() to see a demo.
